QuantumScape ha probado las \u00faltimas celdas de bater\u00eda de estado s\u00f3lido en sus laboratorios de Alemania. Se trata de un hito para la empresa, ya que cumpli\u00f3 el requisito para que Volkswagen AG invirtiera otros $100Mn.<\/p>\n
VW hab\u00eda anunciado la inversi\u00f3n de $200 millones (170 millones de euros) el pasado mes de junio seg\u00fan se informa<\/a>pero en aquel momento s\u00f3lo desembols\u00f3 el primer tramo. Esto eleva la inversi\u00f3n total de Volkswagen en QuantumScape hasta la fecha a $300 millones (255 millones de euros).<\/p>\n \"Nos complace informar de que las c\u00e9lulas QuantumScape cumplieron en nuestros laboratorios de Alemania los hitos t\u00e9cnicos que hab\u00edamos acordado previamente\", declar\u00f3 Frank Blome, responsable del Centro de Excelencia de Bater\u00edas Celulares del Grupo Volkswagen. \"La consecuci\u00f3n de este hito es un paso importante para QuantumScape, y estamos deseando recibir y probar las siguientes generaciones de c\u00e9lulas para llevar la tecnolog\u00eda de estado s\u00f3lido a la producci\u00f3n en serie\".<\/p>\n Ni Blome ni QuantumScape especifican en qu\u00e9 consisten estos \"hitos t\u00e9cnicos\". El especialista en bater\u00edas de estado s\u00f3lido public\u00f3 por primera vez los datos de rendimiento de las c\u00e9lulas prototipo el pasado mes de diciembre, afirmando que mejoraban la autonom\u00eda ofrecida en un 80% en comparaci\u00f3n con las actuales c\u00e9lulas de iones de litio. Los californianos tambi\u00e9n afirmaron que las c\u00e9lulas permitir\u00edan una carga del 80% en 15 minutos y m\u00e1s de un 80% de capacidad restante de la bater\u00eda tras 800 ciclos. La bater\u00eda supuestamente tambi\u00e9n cubre un rango de temperaturas que desciende hasta los -30 grados cent\u00edgrados.<\/p>","protected":false},"excerpt":{"rendered":" QuantumScape ha probado las \u00faltimas celdas de bater\u00edas de estado s\u00f3lido en sus laboratorios de Alemania.

Whether these cells were the same tested for VW was not announced officially but is likely.<\/p>\n In February, QuantumScape had announced the construction of a pilot plant called QS-0 in San Jos\u00e9, California. A few days ago, the company also issued 13 million new shares as reported<\/a>. At the time, the announcement to the SEC included plans for a second pilot plant named QS-1 to be built together with VW. The planned capacity is one GWh with an expansion to 21 GWh for series production. The site of the second battery cell plant is unknown at this time.<\/p>\n Volkswagen had announced plans for a unified battery cell format in 80 per cent of its electric vehicles by 2030 at the ‘Power Day’<\/a> in March. The prismatic cell can host different cell chemistries (LFP, NMC and high-manganese cathodes) adapted to the specific vehicle. At the time, Blome described solid-state batteries as the ultimate goal and targeted a charge time of “just 12 minutes” for an 80 per cent charge. Blome added that QuantumScape had managed the proof-of-concept but has yet to overcome hurdles on the way to industrialisation.<\/p>\n Volkswagen and QuantumScape have been working together since 2012; prior to a 100-million dollar investment in 2018, VW already held five per cent of QuantumScape. Adding the recent 200 million dollars, VW has since become the largest automotive shareholder of the battery specialist, a spin-off from Stanford University.<\/p>\n
